Abstract: 2.1 To improve the "rewind" search mode, on modern recorders which operate by the helical-scan method the capstan shaft is arranged on the drive chassis outside the region intended for the tape cassette. However, with the capstan shaft arranged in such a way, the control mechanism and structural design for actuating the pinch roller are also relatively elaborate. The object is to provide a pinch roller actuating device which can be produced inexpensively and with which frictional losses which lessen the pressing force for the pinch roller against the capstan shaft can be reduced. 2.2 The actuating device, which can be swivelled about a swivel axis (423), essentially comprises a pressure lever (3), bearing the pinch roller (30), a drive lever (42) and an intermediate lever (41), by means of which a spring (5), provided as an energy store for pressing the pinch roller (30) against the capstan shaft (14), is prestressed. Arranged parallel to the pinch roller (30) on the pressure lever (3) is a conically shaped lift roller (35), by means of which, in interaction with a second guide (75), a lifting movement can be superimposed on the swivelling movement of the actuating device. 2.3 In particular for video recorders in which the capstan shaft is outside the cassette region and the pinch roller in the position of rest is sunken in a clearance in the cassette. <IMAGE>

Abstract: PURPOSE:To obtain an accurate and reliable recognition result. CONSTITUTION:A feature parameter extraction part 2 extracts a feature parameter from an input voice from a voice input part 1. Standard parameters of registered voices are registered in a dictionary 3 and a recognition part 4 finds the similarity of the extracted feature parameter to the standard parameters, parameter by parameter. Then the similarity of each parameter is weighted while the characteristic of reliability regarding the similarity or nonsimilarity of the parameter is reflected to calculate the total similarity or nonsimilarity between the input voice and registered voice, thereby recognizing the input voice according to the similarity or nonsimilarity.

Abstract: A monolithic integrated circuit chip preferably includes a pair of data busses capable of conducting in parallel the number of signals which can be processed simultaneously by the components on the chip. Signals on the busses are carried in a time-multiplexed manner, each bus having a pred. etermined number of time slots. Preferably, each component on the chip is connected to one or both of the busses and is assigned a particular time slot for the bus to which it is connected. The resulting chip is of a structured, rather than a custom, design. Accordingly, it can be readily expanded or contracted in the number of signals which can be simultaneously processed. The number of components which can be included on the chip is limited only by the number of time slots available on the bus to which it is connected. By providing two busses, such common circuit elements as two-input adaer subtracters can be readily accommodated by a chip designed according to the instant invention. The bit-slice organization of the chip significantly reduces the design effort of the components connected to a bus, since a one-bit slice is merely replicated for each conductor of the bus. Ease of expansion along this dimension is achieved at virtually no cost.

Abstract: The targets for cathodic sputtering according to this invention are formed of hot-pressed or hot isostatic-pressed indium oxide/tin oxide powder with a minimum density of 95% of the theoretical density and with a sub-stoichiometric oxygen content are known. In order to provide the improvement of high stability and, simultaneously, high sputtering rate, it is proposed according to the invention that the target have a crystalline phase which is formed as a solid solution of indium oxide and tin oxide with a minimum of 90% by weight, preferably a minimum of 97%, of the solid solution, and which has an average grain size ranging from 2  mu m to 20  mu m. In order to make available a simple and cost-efficient method for producing a target consisting of a starting powder of indium oxide/tin oxide, which allows for a precise setting of the oxygen content and a homogeneous chemical composition throughout the entire target volume, it is proposed that a starting powder be used that is produced by oxidizing finely distributed indium tin metal.

Abstract: In an electro-fusion welding process a fault, e.g. due to incorrect assembly of the pipe joint components, is detected by sensing the welding current and emitting a signal to actuate an audible or visible alarm and/or to interrupt the welding process, if the welding current increases unexpectedly. A reference signal dependent upon the current dependent signal produced by the sensor (1) and RMS to DC converter (2) at a time t, is held by a converter (5) and is compared by a comparator (7) with the current dependent signal transmitted through converter (6) at subsequent intervals. So that the device does not react to transient current increase a delay arrangement (9-12) delays the output signal for a given time.

Abstract: A process for making cellulose acetate from wood pulp takes wet wood pulp and instead of converting it into dry pulp sheet which is the usual feedstock for acetate, dries and mechanically separates the pulp into a cellulose flock using a pin mill through which a hot drying gas is passed. Deactivation of the cellulose is avoided by control of the drying gas exit temperature to 80 DEG C to 95 DEG C and of the moisture content of the cellulose flock to 4 to 15% by weight. The flock produced may be acetylated directly without any need for reactivation treatments additional to the normal activation with acetic acid.

Abstract: A computer method and system for allocating memory for a plurality of software routines. Before execution of the software routines, a collective buffer is allocated. Each software routine is assigned an offset within the collective buffer. Each software routine may then use the portion of the collective buffer starting at its offset as its dynamically allocated work space. To allocate the collective buffer, a collective buffer size is first determined which is sufficient to satisfy the total dynamic memory requirements of the software routines. In determining the collective buffer size, the size of a software routine buffer required by each software routine is accumulated into the collective buffer size. As each software routine buffer size requirement is accumulated, the interim total is stored as the offset for the next software routine. When the last software routine buffer size requirement is accumulated, the total indicates the collective buffer size. A collective buffer of the collective buffer size is then allocated. When the software routines are executed, each software routine uses a portion of the collective buffer referenced by its assigned offset. When all the software routines complete execution, the collective buffer may then be deallocated. In a preferred embodiment, the memory is allocated to a software system having a layered architecture including an application program and a device driver comprising a plurality of component device drivers. <IMAGE>
